Battery Materials

The current battery king, the lithium-ion battery, has been the battery of choice for portable electronics for many years because of its high energy density and decreasing production costs. However, these market leaders have some significant limitations. Stability and safety are, of course, the most high-profile concerns with these batteries, but size, capacity, and cost are also areas of concern. In the case of electronic vehicles, (EVs), lithium-ion batteries make up a considerable portion of the mass and volume of the EV, require frequent recharging, and they make up a high portion of the cost of these vehicles. The market’s demand for batteries that are safer and that have a higher energy density and lower production cost than current lithium-ion batteries is high. As a result, battery technologies are being improved upon at a rate perhaps never before seen.

ACS materials is at the leading edge of this research with our silicon nanoparticle anode materials.

For example, our Si/C Composite anode material has a higher specific capacity than lithium ion alone, a cycle performance that can reach 1500 cycles, and a capacity retention rate up to 80%. This product has achieved industrialization ton scale, and has been applied in some well-known factories. Batteries constructed with these nanostructure particles have greater structural stability and higher specific capacity than traditional lithium-ion batteries. Silicon nanostructure particle anodes are the future of battery technology.
